I have the same issue as @tonylambiris with the latest commit e65de5a.

I have the same issue and after some digging I was able to make it work by disabling the color palette setting in MainWindowWithDetachableDockWidgets::updateActiveDockWidget() in src/ui/mainwindowwithdetachabledockwidgets.cc:
QList<DockWidget*> dock_widgets = findChildren<DockWidget*>();
for (auto dock_widget : dock_widgets) {
if (false && mark_active_dock_widget_ && active_dock_widget_ == dock_widget) {
dock_widget->setStyleSheet(
QString("%1::title {"
"background : palette(highlight);"
"color : palette(highlighted-text);"
"}")
.arg(QString(dock_widget->metaObject()->className())
.replace(':', '-')));
} else {
// always force emptystylesheet
dock_widget->setStyleSheet("");
}
}It seems to be related to Qt palette ( I also get these messages :
qt5ct: using qt5ct plugin
qt5ct: D-Bus global menu: no
qt5ct: palette support is disabled)
No idea how to really fix this though, and it will still crash if you try dragging parts of the window. Any ideas ?
